Im getting there at last.

Dma was already done but when you say disable desktop do you mean view as webpage ?

Also the swap file is on the same drive as the ati software but im capturing to a spare defragged empty hard drive - fat 32, should the sawp file be on a different drive than the ati software and drivers ?

Sorry to be a pain but im closer to my goal at last, which is solving the problem without dipping into my wallet

Cheers
